Issue using wmediumd

[masad8]

Hi,

I am using Mininet-WiFi using Python API. Everything sees to be working fine except the wmediumd. I have installed wmediumd along with Mininet-WiFi installation, however, when I use wmediumd in Pythons script, I get the following error:

Connecting to wmediumd server /var/run/wmediumd.sock
Traceback (most recent call last):

  File "/usr/lib/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 2] No such file or directory

Can you please tell what could be the issue?

AFAIK, the message socket.error: [Errno 2] No such file or directory means that either you haven't installed wmediumd or you are using other wmediumd version than that one provided by util/install.sh -l.

I am using Python 2.7, and also I installed mininet-wifi using sudo util/install.sh -Wlnfv. This should probably the correct version of wmediumd?

[ramonfontes]

Wmediumd is written in C. So the python version won't be a problem. sudo util/install.sh -Wlnfv installs the correct version. I suggest you to make sure that your system has installed wmediumd correctly. In other words, that no error was encountered during its installation.
